Title: Impedance matching for a dual band power amplifier
Inventor: PECKHAM DAVID SUTHERLAND
IPC: H04B1/40
Filed: 1998-01-21
Abstract: An exciter matching circuit (125), interstage matching circuit (134), and harmonic filter matching circuit (140) match impedances at the input to a two-stage power amplifier (130), between the first stage (132) and the second stage (136) of the power amplifier (130), and at the output of the power amplifier (130) for more than one frequency band of interest. In a GSM/DCS dual band radiotelephone (101), the matching circuits (125,134, 140) provide low return loss at 900 MHz when the dual band transmitter (110) is operating in the GSM mode. The harmonic filter matching circuit (140) also filters out signals at 1800 MHz, 2700 MHz, and high order harmonics. When the dual band transmitter (110) is in DCS mode, however, the matching circuits (125, 134, 140) provide a low return loss at 1800 MHz and filter out signals at 2700 MHz and harmonics of 1800 MHz.

Title: A toy
Inventor: DEKKER NICOLAS PETRUS
IPC: A63F9/08
Filed: 1998-01-28
Abstract: The present invention relates to a toy and a method of manufacture of the toy. In particular, the present invention relates to a toy made from sheet material 10, wherein by folding the toy, a plurality of different images may be exposed. The toy is foldable or unfoldable about at least one defined fold or unfold axis (45, 47, 57, 59 Figures 5 and 6). In an unfolded state, the toy has only two fold axes (45, 47). During folding or unfolding, the toy has only one fold axis about which the folding or unfolding is occurring. In a folded state, the toy has only two unfold axes (57,59). The method of manufacture comprises taking a sheet 10 of material having three tabs 20, 22, 24, attached thereto; folding the tabs 20, 22, 24 inwards towards the centre of the sheet 10, so that first faces of the three tabs 20, 22, 24 face the same face of the sheet 10; folding the sheet 10 in half to envelope the tabs, and attaching to the face of the sheet the second faces (37 Figures 3 and 4) of the tabs 20, 22, 24. The present invention also relates to a sheet (10) for using in a manufacturing process according to the present invention. The toy is suitable for use as a promotional item in e.g. cereal packets, as an information carrier or as a puzzle or game.

Abstract: A current sensing circuit (50) for use in an ADSL interface circuit senses an input current (IL) flowing through a resistor (R1) and provides an image output signal at an output which is an image of the input current. The circuit comprises an input stage (56) having a first input terminal for coupling to one terminal of the resistor (R1), a second input for coupling to the other terminal of the resistor and first (57) and second (58) output terminals, a first P-type current mirror (60) having an input terminal, an output terminal and a supply terminal, the input terminal being coupled to the first output terminal (57) of the input stage (56) and the supply terminal being coupled to a first supply line, a second N-type current mirror (62) having an input terminal, an output terminal and a supply terminal, the input terminal being coupled to the second output terminal (58) of the input stage (56) and the supply terminal being coupled to a second supply line and combining means (63) coupled to the output terminals of the first and second current mirrors for combining the output signals at the output terminals of the first and second current mirrors to provide the image output signal. The circuit further comprises bias means (R101, R102) for biasing the input stage to operate in class AB such that the input stage provides a transconductance which tends to increase with increasing level of the input current, and offset means (R103, R109, R115) for generating offset voltages in the first and second current mirrors which cause the gains of the current mirrors to tend to reduce with increasing level of the input current such that the combined gains of the input stage and the first and second current mirrors remain substantially independent of the level of the input current.

Title: Latency time determination system for an infra-red transceiver
Inventor: SKURDAL VINCENT C
IPC: H04B10/08
Filed: 1998-08-11
Abstract: A system (26, 2, 24, 16, 18, 10) to determine the length of time, known as the latency time, that is required to wait between transmitting and receiving data for a half-duplex electromagnetic transceiver (4) having a transmitter (8) and receiver (6) wherein the receiver is electromagnetically coupled to the transmitter. The determination of the latency time is accomplished by the use of a control circuit (2) that operates to turn the transmitter (8) to an on state. The control circuit (2) then monitors the receiver (6) to determine when the receiver (6) also goes to an on state due to the electromagnetic coupling. The control circuit subsequently turns off the transmitter (8) and the length of time for the receiver (6) to recover to an off state is measured. This length of time is the latency time and is used in subsequent transmission of data. The transceiver operates in the infra-red.

Title: Jitter reduction in a digital to analog converter
Inventor: SCHOFIELD WILLIAM GEORGE JOHN
IPC: H03K17/693
Filed: 1998-09-04
Abstract: Digital circuitry, for use in a digital-to-analog converter, has decoders (22, 24) which process a digital input word (D1 Dm) to derive thermometer-coded signals (T, <O>T</O>) for controlling one cell 30 of an array of cells. The decoders (22,24) commence operation at the rising edge of a first clock signal (DIGCLK). Each cell has a first, D-type latch (26) clocked by a second clock signal (CLK2) that is delayed by a preselected delay time   W  <SB>1</SB> relative to the first clock signal, and a second, transparent latch (32) clocked by a third clock signal (CLK3) whose rising edge coincides with the rising edge of the first clock signal and whose falling edge coincides with the rising edge of the second clock signal. The rising edge of the third clock signal is not affected by jitter associated with a delay element (28) used to delay the first clock signal by   W  <SB>1</SB>. The falling edge is affected by such jitter, so outputs (TCK, <O>TCK</O>) of the first latch (26) have jitter at the falling edge, but this is presented from feeding through to final outputs (TS, <O>TS</O>) of the circuitry because the second latch (32) is non-transparent at that falling edge.

Abstract: A display window 12a for a communication device such as a mobile or car phone (3; figure 1) has a matt surface structure. It is produced by providing an injection moulding tool, which preferably comprises two parts 20,21, with a mail surface structure, the mail surface structure preferably being applied to the moulding tool by electro-erosion. Preferably, the mail surface structure is only applied to one surface 21a of the moulding tool part 21, so that the front face (12aa; figure 2) of the display window 12a has the matt surface structure. Preferably, the mail surface 21a of the moulding tool 21 is structured with a roughness of 1m or finer. The display window 12a is preferably made of an acrylic plastic. The display window 12a improves the visibility of information presented on a display element (12b; figure 2) which is covered by the display window 12a because the disturbing effect of light reflections on the display window 12a is reduced.
